They may seem like automatons, but ants are surprisingly sophisticated in their navigational strategies.

- Carpenter ants use diverse antennae sampling strategies to track odor trails | Journal of Experimental Biology, 28.09.2018 http://jeb.biologists.org/content/early/2018/09/27/jeb.185124
"... In this study, we use high resolution videography to characterize the antennae dynamics of carpenter ants (Camponotus pennsylvanicus). Antennae are highly active during both odor tracking and exploratory behavior. When tracking, ants used several distinct behavioral strategies with stereotyped antennae sampling patterns (which we call Sinusoidal, Probing, and Trail Following). In all behaviors, left and right antennae movements were anti-correlated, and tracking ants exhibited biases in the use of left vs right antenna to sample the odor trail. These results suggest non-redundant roles for the two antennae. (...)"
